About HW group

Who are we

HW group s.r.o. company is Prague based (Czech Republic) manufacturer of a remote monitoring ecosystem. We produce the whole system from hardware (sensors & devices) to software or related services. The company started in 2003. Our portfolio consists now of more than 300 different product items and we distribute them globally with a network of 50 distributors.

Our products are used for remote monitoring of data centers, Covid vaccines freezers, technology rooms, and similar. It’s used also for energy consumption metering.

We offer a simple-to-install RME (Remote Monitoring Ecosystem) with IP-connected devices. Our RME can be scaled from a single device up to a robust network of hundreds of devices. Growing with projects of our customers, our RME system is industrial grade, secure, and proven in projects ranging from small installations up to large-scale deployments with hundreds of devices and users.


  • Our products have a lifetime of 5-15 years. All this time it has to be reliable in monitoring & alerting.

  • Even after 5 years of no activity, the alerting has to be reliable. If there is water leakage, for example, every second counts.

  • Our customers are not buying just temperature probes. Our customers are buying assurance that everything is OK in their remote location.

What do we do

The main focus of the HW group company is RME (Remote Monitoring Ecosystem). Many customers are using just 2-3 devices with a few sensors, but we also have installations with several hundred devices and thousands of sensors in one project.

  • 70+ different Sensors & Detectors (Temperature, Humidity, Voltage, Energy, …)
  • 30+ device types you can use as Standalone or with the portal
  • Various IP connectivity: LAN, WiFi, GSM, LTE, NB-IoT
  • SensDesk Technology portal (SaaS / on-premise)
  • Our RME (Remote Monitoring Ecosystem) can be used with or without our portal
  • Most of our products have documented Open API to be easily integrated with 3rd party systems.



Our Standalone Monitoring products can be used with or without our monitoring system. Without the portal, it can send you an email, SMS, or SNMP Trap alert when, for example, the temperature exceeds the limit. With the paid portal you get all the extra features like reports, multigraphs, dashboards, etc. Our IT professional customers love how fast & easy our devices can be installed.




Products we call IoT Monitoring are designed to be easily installed without professional stuff on the site. Cost-effective installation and central device management are the advantages of the portal-based system. The SensDesk Technology portal is something you can use as a SaaS cloud service or install on your own server (on-premise).

Technical standards


Our final products are produced in Europe and conform to all European and FCC standards.


EC guideline (RoHS)

The EC "Restriction of Hazardous Substances in Electrical & Electronic Equipment" (RoHS) guideline has been released in order to reduce the heavy metal load in electrical and electronic products caused by e.g. lead and mercury. All manufacturers are obligated to provide only RoHS-compliant products to the European market, effective from July 1st, 2006.


In cooperation with our suppliers, all relevant products are currently redesigned to comply with the EC guideline. Thus, HW group s.r.o will be able to deliver some RoHS-compliant products already before the guideline's official commencement of July 1st, 2006 (probably April 2006).

HW group s.r.o. fully reflects politics which restricts usage of so-called conflict minerals (3TG) which includes tantalum (Ta), tin (Sn), tungsten (W), and gold (Au) with origin from the Democratic Republic of Congo (DRC) or adjoining country (conflict areas).

Mines of these minerals in the DRC which are controlled by non-government military groups or unlawful military fractions the coverage of human rights violations (such as forced labor) in the DRC and environmental issues resulting from the extraction of minerals.
